Strains of Staphylococcus aureus were isolated at a single sampling from cows in a dairy herd. When typed by phage most showed a complex pattern of lysis with group III and IV phages. Cross-spotting of strains showed great lytic activity and ten phages were isolated. The parent strains were lysogenized with these phages and the effect on the phage typing pattern of 202 daughter strains from 25 parent cultures was studied. Phage action was often blocked completely, with up to four being blocked on the one strain. Those most frequently blocked were phage 101, 117, 367 and 42D.
从一个奶牛场的奶牛中单次采样分离出金黄色葡萄球菌菌株。用噬菌体分型时，大多数菌株表现出与III组和IV组噬菌体的复杂裂解模式。菌株的交叉斑点试验显示出很强的裂解活性，并分离出10种噬菌体。用这些噬菌体对亲代菌株进行溶源化处理，并研究了25个亲代培养物中202个子代菌株的噬菌体分型模式的影响。噬菌体作用常常被完全阻断，一个菌株上最多有4种噬菌体被阻断。最常被阻断的噬菌体是101、117、367和42D。
